AI can write code. Having an internal model of _how_ it runs is important more than ever.

Learn WebAssembly: interactive, in-browser exercises with a debugger + memory inspector.

Perfect timing to use that leftover learning budget.

Node excitement ๐Ÿ˜‰

Congrats to @marcoippolito.dev on making it official: type-stripping in Node 25 is now declared to be stable ๐ŸŽ‰

You can run: node index.ts

The capabilities have not changed since Node 24. This is purely a maturity indicator.

Since I am getting a lot of PPP requests I decided to make my #WebAssembly course more affordable for a limited time.

Grab it while it's available.
